Product activation

Authorization determines whether the client can be started and the range of functions available. This page describes the preparation materials, inputs, and FAQs for Fixed MAC Address Activation and Floating License Activation; see Installation Steps for the installation process.

Two ways to activate

Matches	Fixed MAC Address Activation	Floating License Activation
Authorization source	A license file tied to the machine	License Server Uniform Assignment
Preparation required	License file issued with local information	Server address and port number of License Server
Action Portal	Import License in the Activation Certificate Dialog Box	Server Address, Port and Connections in the Activation Certificate Dialog Box
Applicable scenarios	Stand-alone use, authorization, and binding to fixed devices	Frequent changes in shared authorization pools, devices, or accounts for multiple people

Both are done in the activation certificate dialog that pops up the first time you start the client, no additional components need to be installed.

Activate with Fixed MAC Address

1. In the Start menu, find Datablau Data Modeler and launch the application.
2. In the Activate Certificate dialog that pops up, click Import License.
3. Select the license file path corresponding to the machine to complete the import.
4. After the import is successful, go to the client homepage; if it fails, check whether the file issued by the local machine is used.

Activate with Floating License

1. Launch the application and enter the server address and port number of the DDM License Server in the Activation Certificate dialog box.
2. Click Connect and the client requests authorization from the authorization service.
3. After the connection is successful, enter the client's home page; when the connection fails, first confirm the network is reachable, and then check the address and port.

Input check

Inputs	Checkpoints
license file	Is it issued for the current device, is the file complete, has it expired
Server address	Can be accessed locally, complete service address instead of page address
Port Number	Is it consistent with the actual listening port of the authorized service
Authorization mode	Choose real-time mode or loan mode, whether it matches the way the team uses it

Real-Time Mode vs. Rental Mode

Mode	Release Timing	Suitable for
Real-time mode	Automatically return license resources after closing the DDM program	Fixed usage period, want to release the authorization at any time
Rental mode	License resources are released after expiration, early return requires manual shutdown	Offline or continuous use for a period of time

When choosing the rental mode, if you no longer use the client, you should take the initiative to close it to return the resources in advance, so as to avoid other members from being unable to obtain authorization for a long time.
